h-BN layer induced chiral decomposition in the electronic properties of multilayer graphene
Ilona Zasada, Andrzej Molenda, Paweł Maślanka +1
We discuss the chiral decomposition of non-symmetric stacking structures. It is shown that the low-energy electronic structure of Bernal stacked graphene multilayer deposited on h-…
QED2+1 in graphene: symmetries of Dirac equation in 2+1 dimensions
P. Kosinski, P. Maslanka, J. Slawinska +1
It is well-known that the tight-binding Hamiltonian of graphene describes the low-energy excitations that appear to be massless chiral Dirac fermions. Thus, in the continuum limit…
Domains of doping in graphene on polycrystalline gold: first-principles and scanning tunneling spectroscopy studies
J. Slawinska, I. Wlasny, P. Dabrowski +2
We have studied the graphene/gold interface by means of density functional theory (DFT) and scanning tunneling spectroscopy (STS). Weak interaction between graphene and the underly…
Fingerprints of Dirac points in first-principles scanning tunneling spectra of graphene on a metal substrate
J. Slawinska, I. Zasada
Graphene physisorbed on a metal has its characteristic Dirac cones preserved in the band-structure, but the Fermi level of the system is shifted due to the interaction with the sub…
Doping of graphene by a Au(111) substrate: Calculation strategy within the local density approximation and a semiempirical van der Waals approach
J. Slawinska, P. Dabrowski, I. Zasada
We have performed a density functional study of graphene adsorbed on Au(111) surface using both a local density approximation and a semiempirical van der Waals approach proposed by…
Comment on "Tunable Band Gaps in Bilayer Graphene-BN Heterostructures"
J. Slawinska, I. Zasada, P. Kosinski +1
We study the electronic properties of h-BN/graphene/h-BN ABC-stacked trilayer systems using tight binding and DFT methods. We comment on the recent work of Ramasubramaniam et al. (…
